Can't see images with Firefox ...

This isn't related to the site but more to my setup ... but I have no idea where to start. I recently updated Firefox ... and now I can't see any images from 6Speed (although it works perfect with IE ... which is how I created this thread) ... can't see the banner up top, can't see the sponsors on the side, can't see the avatars, can't see the new thread/reply/edit/quote buttons ... etc. I can see however the hotlinked images.
Cleared the cache and made sure I didn't block images from 6Speed ... everything seems right.
